Portable children&#39;s toilet system

ABSTRACT

A portable children&#39;s toilet system, a handheld children&#39;s toilet kit and a pram is disclosed. The portable children&#39;s toilet system includes a collapsible children&#39;s toilet and a collapsible privacy screen, for providing privacy to a child using the collapsible children&#39;s toilet. Advantageously, the portable children&#39;s toilet system is easy to carry, for example on a pram, and can be used on demand. As such, reliance on public toilets is avoided.

TECHNICAL FIELD

The present invention relates to a portable children's toilet system, and in particular, although not exclusively, to a portable children's toilet system including a privacy screen.

BACKGROUND ART

When away from home, suitable toilets are often hard to come by, which can cause problems, particularly when children are involved. In some cases, a child may be forced to go to the toilet in a sub-optimal environment, which can cause distress to the child or a parent. In other cases, trips may be prematurely ended or substantially altered due to a lack of a suitable toilet in the area.

Public toilets (referred to as public restrooms in the United States) are often crowded and dirty, and may not be suitable for children. Furthermore, public toilets are often gender specific, which can cause problems if, for example, a father needs to take a girl into a male toilet.

Furthermore, at parks, beaches, playgrounds and the like, public toilets are often simply not available at all. In certain cases, a closest suitable public toilet may be several kilometres away. As such, the use of public toilets cannot be relied upon when travelling.

Portable camping toilets exist, for example in the form of chemical toilets and toilets with disposable receptacles. Such toilets are often used inside a caravan or motorhome, and are particularly advantageous when travelling.

A problem with such portable camping toilets of the prior art is that they are generally bulky. Furthermore, such portable camping toilets do not provide any privacy and thus must be used inside a caravan or other private area, or alternatively used openly and without any privacy.

Toilet and shower tents exist for camping, which provide privacy for a portable toilet or shower. Such tents are generally spacious, typically over 2 m high and with a floor area of over 1 m². As such, these tents are generally quite bulky, and are thus often used only for specific camping trips.

It will be clearly understood that, if a prior art publication is referred to herein, this reference does not constitute an admission that the publication forms part of the common general knowledge in the art in Australia or in any other country.

FIG. 4 illustrates a perspective view of a collapsible children's toilet 400, according to an alternative embodiment of the present invention. The collapsible children's toilet 400 is similar to the collapsible children's toilet 105 of FIG. 1, and can be provided to children when and where needed.

The toilet 400 includes a seat portion 405, a front support leg 410, and a rear support 415. The front support leg 410 comprises a leg portion 410 a and a base portion 410 b, wherein the leg portion 410 a and the base portion 410 b form an inverted T shape. The leg portion 410 a is pivotally attached to a front of the seat portion 405, which enables the front support leg 410 to fold backwards under the seat portion, as illustrated with reference to FIG. 5.

The rear support 415 comprises two leg portions 415 a, pivotally attached to a rear of the seat portion 405, and a base portion 415 b. The rear support 415 is generally U-shaped and pivots forwards under the seat portion 405, as illustrated with reference to FIG. 5.

The toilet 400 further includes a disposable bag 420, for receiving excrement and/or urine from the child. The disposable bag 420 is similar to the disposable bag 115, and may include an absorbent material (not shown) on an inside of the disposable bag 420.

As illustrated in FIG. 5, the disposable bag 420 may be installed to the toilet 400 when folded up, to simplify and speed up the installation process. Furthermore, the toilet may include catches, to prevent the toilet from unfolding when folded up.

As illustrated in FIG. 6, the seat portion 405 tapers from a rear of the seat portion 405 to a front of the seat portion 405 in a plane of the seat. In other words, the rear of the seat portion 405 is wider than the front of the seat portion. As such, a relatively wide rear of the seat portion 405 provides stability, while a relatively narrow front of the seat portion 405 provides a comfortable width for the child.

As illustrated in FIG. 7, seat tapers from rear to front in that the rear of the seat portion is thicker than front. This ensures that sufficient strength is provided to the rear support 415, which providing a comfortable surface for the child. Similarly, an opening 425 of the seat portion 405 graduates smoothly from a flat upper surface of the seat portion 405.

FIG. 8 illustrates a bottom view of the toilet 400, when folded away. A plurality of bag retainers 430 extend around a periphery of the opening 425, for retaining the disposable bag 420. The bag retainers 430 comprise clips for receiving an upper edge of the bag 420 and preventing the bag from falling downwards. The bag 420 may include a rigid or semi rigid upper lip (not illustrated), conforming to an inside of the opening 425 and assisting in retaining the bag 420 and preventing leakage from between the seat portion 405 and the bag 420.

As illustrated in FIG. 9, the toilet 400 is configured such that in use, the seat tilts forwards approximately 8.8 degrees from horizontal. Furthermore, the legs 410, 415 extend outwardly from the seat portion 405, to provide sturdy base and to help prevent toppling of the toilet if the child moves.

The toilet further includes locking buttons 435, for locking and releasing the rear support 415. In particular, the rear support may lock in a closed position by one or more locking members, to prevent the seat from inadvertently opening while in storage. In such case, the locking buttons can be pushed in to release the locking members when in use. The locking members may also lock the legs 410 and/or 415 in an open position, to provide addition rigidity to the toilet 400 when in use.

According to certain embodiments, the base 405 is about 280 mm wide and about 290 mm long. The base may taper from about 39.9 mm thickness at about 4.9 degrees.

FIG. 10 illustrates a carry bag 1000, for carrying the toilet 400, according to an embodiment of the present invention. The carry bag 1000 includes a body 1005, for receiving the toilet 400, and a handle 1010, which is pivotally attached to sides of the body 1005. The handle 1010 enables the bag 1000 be carried in a similar manner to a handbag, or supported by handles of a pram or stroller.

The body 1005 includes an opening on an upper end, for receiving the toilet 400. The opening is advantageously sealable by a zipper, to prevent the toilet 400 from falling out of the bag 1000.

The bag 1000 further includes a disposable bag pouch 1015, for receiving disposable bags 420. The bag pouch 1015 is advantageously configured to receive a plurality of unused bags 420, to enable the toilet 400 to be used several times.

FIG. 11 illustrates a collapsible privacy screen 1100, according to an embodiment of the present invention. The privacy screen 1100 is similar to the tent 110 of FIG. 1, and shields the toilet 400 when in use.

The privacy screen 1100 includes four panels 1105 attached by flexible hinge portions 1110. Furthermore, the privacy screen 1100 includes a releasable retainer, for joining a first and last panel 1105. As such, the panels 1105 may be opened to enable a child to enter and leave a space defined by the panels 1105.

In use, the privacy screen 1100 may define a substantially cubic space. Alternatively, the privacy screen can be used with an end open, providing shielding from one direction. This may be particularly useful when one side is shielded by other means, e.g. by a wall, as it enables a configurable layout.

The panels may be about 837 mm wide by about 812.6 mm high.

According to certain embodiments, each panel 1105 is foldable, for storage in the carry bag 1000. In such case, the panels 1105 may be “self-unfolding”, i.e. such that the panel will expand upon being unpacked from a carry bag 1100 or another storage container/bag.

The bag 1000, the screen 1100 and the toilet 400 comprise a portable children's toilet system, similar to the system 100. In particular, the bag 1000, the screen 1100 and the toilet 400 may be sold in a kit, for easy transportation and use together.

The toilet 400, 105 may be formed primarily of acrylonitrile butadiene styrene (ABS) plastic, to provide a lightweight yet sturdy toilet.
